I've run into a problem, I get this error when trying to activate virtual mode: insufficient disk space on the disk :\. At least...... etc. Yes the letter is missing, under settings it says 'protected disk = :' no letter or anything just the colon, my system partition is c:\ Is there a way (registry, ini file?) to make it recognize that it needs to use this drive for the program to work. Not sure if you need anymore info like that its an EeePC with an OCZ SSD drive. On another install, I've found that if there's a Z:\ drive on your system and you're trying to install or run returnil it will just silently fail, the service won't start and it tells you nothing at all (other than the service is not running). I renamed the drive letter and it was ok. A warning would help techs and customers out a lot in this situation. It'd be even better if you could select the drive letter it want's to lockdown (or even be able to use the letter if it's not actually being used at all by the program). Modern systems are less and less using floppy drives.. A: and especially B: are practically obsolete with the invent of usb drives.
